UNITED STATES PATENT ARTHUR I MURPHY, SR., INDEPENDENCE, MISSOURI.

LOOSE-LEAF BOOK.

Be itknown that I, ARTHUR L. MURPHY, Sn, a citizen of the United States, residing at Independence,'in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Loose-Leaf Books, of which the following is a specification.

My invention relates to improvements in loose leaf books.

The object of my invention is to provide a loose leaf book which is simple in construction, easy to operate, is not liable to get out w book providedwith my invention and shown straight,

in planin the open position, the books h eing shown in the closed positions. Fig. 2 is a cross section on the dotted line ab of Fig. 1. .Fig. 3 is a bottom viewof the hook supporting member and parts connected therewith. Fig. 4 is a perspective view of the flanged plate which forms the back of the book and supports the hook plate.

Similar reference characters denote similar parts. I 1 denotes a longitudinal plate which forms the back of the book and to which the covers 2 are hinged in any suitable manner, as, for

instance, by flexible binding material 3. 4 is a fiat longitudinal plate disposed lengthwise in the concave inner side of the plate 1, the latter plate having at opposite edges longitudinal flanges 5 which respectlvely embrace opposite edges of the plate 4.} The plate 4, which is the hook supporting member, is provided with a plurality of holes 6 in which are preferably respectively secured one set of ends of one or more flexible hooks, preferably comprising coil springs 7 composed of wires formed having superimposed coils, the .free ends of which have respectively secured in them securing devices, preferably comprising pins 8 adapted re spectively to enter holes 9 provided in the member 4, the pins having each a lateral notch 10 adapted to receive the plate 4 to hold the hook when the pin is in the hole 9. The coil springs 7 are preferably normally as shown in dotted lines in Fig.2,

to enable the leaves 11 to be more-easily inserted upon and withdrawn from the hooks when the hooks are in the open positions, the leaves 11 being each provided with holes 12 to receive the hooks 7.

To release the pins from the locked position, shown in'Figs. 1 and 2 the following mechanism is preferably provided :--A longitudinal member comprising preferably a flat bar 13 is located between the plates 1 and 4 and is longitudinally slidable in holes provided in projections'14 which extend toward the plate 1 from the plate 4. I The projections 14 are preferably formed by cutting tongues in the plate 4 and then bending said tongues at right angles to the plate. The bar 13 preferably has an end projecting beyond' the plates 1 and 4, the projecting end" being provided with a button 15 by which the bar is grasped to. bemanipulated. The

bar 13 is provided, referably with lateralv recesses 16 in one e go through which the pins- 8 extend when in the closed posltion.

By. drawing-the bar 13 outwardly the bar will strike the pins 8 and force them in the holes 9 to positions in which the plate 4 will be disengaged from the notched port-ions of said pins. If, as is the case in the preferred form of my invention, the hooks 7 are of resilient material, the hooks on being released will spring to the straight position, shown in dotted lines in Fig. 2, when leaves may be readily removed from or placed upon the hooks. A coil spring 17 having one end secured to a projection 18 on the plate 4 and the other endsecured to a projection 19 on the bar 13 serves to retract the bar to the position shown in Fig. 3, in which the pins 8 are free to enter the holes 9 and engage the plate 4.

When the leaves are placed on the hooks, the hooks are inserted in the holes 9, when the resiliency of the springs 7 will cause the pins to move to positions in which the plate 4 will enter the notches 10, thereby holding the hooks in the closed positions.

Preferably the plate 4 is of such form that when the hooks are moved to the closed positions, the springs 7 will assume a curved position, as shown in Fig. 2, thus permitting ways, within the scope of the appended claims, without departing from its spirit.

Having thus described my inventlon, what ent is 1. In a loose leaf book, the combination with a supporting plate, of a hook comprising a coil spring secured at one end to said late and a locking device secured to the rec end of said spring and having means for releasably' engaging said plate, a member movable to and from a position in which it will release said device from said plate and means for retracting said member from said position. Y

2. In a loose leaf book the combination with a supporting plate having a hole, of a hook comprising a coil spring secured at one end to said plate and a lockin device secured to the free end of the spring and adapted to enter said hole and engage said plate, a member movable to and from a position in which it will release said device from said plate and a spring for retracting end to said plate and a locking device secured to the free end of said spring and adapted to enter said hole and engage said plate, and a member slidable to and from a position in which it will disengage said de-' vice from said plate; &

4.1In a loose leaf book, the combination with a supporting plate having a plurality of holes, of a plurality of hooks comprising coil springs secured at one set of ends to I said plate and a plurality of devices secured respectively to the free ends of said springs for entering said holes respectively and releasably engaging said plate, and means for simultaneously releasing saiddevices from said engagement.

5. In a loose leaf book, the combination with a sup orting plate having a plurality of holes, 0 a plurality of hooks comprising coil springs secured at one set of ends to said plate and devices secured respectively tothe free ends of said springs for respectively entering said holes and engaging said plate, and a member slidable on said plate to and from a position in which it will force devices out of engagement with said plate.

6. In aloose leaf book, the combination with a supporting plate having a pluralityof holes, of a plurality of hooks comprising coil springs secured at onev set of ends to said plate and devices secured respectively to the free ends .of said springs for entering said holes and releasably en aging said plate, a member slidable to and om a position in whlch it Wlll force said devices rom engagement with said plate, and means for retracting said member from said position. In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
